自动丢枪装置在TCP+APR联作测试中的应用

Application of Automatic Throwing Gun Device in Combined Test of TCP+ APR

在TCP+APR试油联作中使用自动丢枪装置可降低起钻风险、减少工作量,但是液柱压力提前进入射孔枪、射孔后炮眼堵塞等意外因素会导致丢枪失败,此外,超过200 m的射孔枪在射孔时产生的冲击力和丢枪瞬间对管柱的作用力会影响封隔器和压力计的正常工作。通过风险分析进行工艺改进,在M-2井试油作业中成功使用自动丢枪装置,测试成功。

Using automatic throwing gun device in try combined oil test technologies of TCP + APR can reduce risk for hoisting up pipe and workload,while,accident factors of liquid column pressure entering shot hole gun ahead,and shot hole jam after perforation will led to failure of lost gun,also,impact produced on condition of perforation with over 200 m of shot hole guns and force on tube pipe when losing guns influence normal work of packers and pressure gauges. Through risk analysis and process improvement,device of automatically lost guns has been applied in the M-2 oil well operation successfully,and its test is successful.
